BOBBIN-WINDING IVIAGI-IINE.

Application filed October 30, 1922. Serial No. 598,008.

To all whom it may concern:

Be itjknown that I, JAMES D. Joron, citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements inBobbin-Winding Machines, of which the following is a specification.

This invention relates to upright spindle winding machines known as bottle bobbin winders, the object in view being to simplify and improve the existing method of winding on to bottle bobbins and to improve upon the existing method of winding on to cones and conical shaped bobbins by effecting and maintaining a definite, unchanging relationship between the growth in height and thickness of the yarn package and the changing height of the yarn guide known as the builder, and is a refiling ofapplication Serial Number 449,045, filed March 2, 1921.

In order to producea properly wound bobbin it is necessary to have the yarn laid evenly in quantity and-tension from commencement to finish of the package, each layer containing the same quantity in length of yarn and each layer being equidistant from all others-hence the necessity of having the changing height of the yarn guide controlled by the changing height of the yarn package. This should be automatic and dependent rather than independent as is usually the case with geared controls which do not seem to lend themselves to proper adjustment and most certainly do not maintain it where bobbins are of variable thickness.

Heretofore the chief objection to automatic building has been due to the fact that the general construction of the spindle and attendant mechanism would not accommodate itself to defective or broken yarns. Since all yarns are imperfect it is necessary to improve the spindle construction. Such feature is claimed as thebase of this invention or development and speciallv is as follows: In the existing undesirable construction the spindle carrying the bobbin is revolved by means of a disk which is permanently mounted and fixed to the spindle, being rotated by contact with a wheel oper ating and revolving at right angles thereto. (Vere operation continuous, the ob ect1on would not be reached, however, it becomes necessary for purposes of splicing yarns to stop the rotation of the bobbin by raising what will now be recognized as the friction disk up and oft from the friction wheel. Its attendant objection will now be evident since lifting the friction disk which is fixed to the spindle carryingthe bobbin is also lifting the bobbin finally achieving the ulti mate objection of changing the relative height of bobbin and yarn guide. The builder governing the yarn guiderwhen in continuous operation is lightly touched by each additional layer of yarn which through the rotation of the bobbin is turned slightly and being mounted on a threaded stem is causedto rise to the new desired height, which is also the new height of the yarn package, but when the bobbin is stopped, through not revolving, it does not change the height of thebuilder but does change the heightof the bobbin, as previously explained causing heavy contact or bump of yarn package and builder, resulting in case of hard yarn, in a bent builder stem; in soft yarns the package is dented, and in very delicate yarn the strands are stretched and broken; Again, if the builder is lifted by hand to avoid bumping, it consumes time, and. if not returned to its original place commences building at a higher point, re sulting in an uneven package which is extremely undesirable. In continuous operation the existing method is successful, but not successfulwhen the machine as a whole is running but with an individual spindle or spindles stopped, and this because the spindle carrying the bobbin is lifted thereby changing the relation of package and builder. The solution of this problem and the object of this invention is, to lift the friction-disk, thereby stopping the rotation of the spindle and bobbin but without raising the spindle, consequently leaving an unchanged relationship of yarn package and builder avoiding the aforementioned bent builders, dented packages and stretched or broken yarns. V

The invention to effect this consists of the construction, combination and arrangement herein fully described, illustrated and claimed. 1

The improved bobbin windingunitcom- 1." prises a bracket A; having upper and "lower arms "a and a respectively, said arms being formed with upper and lower bearings a and a for a vertical stem or spindle B which rotates freely therein. Any number 'of'bobbin winding units may be mounted in a single machine, the latter being partially shown in Figures 1 and 2 wherein the relation of one bobbin winding unit thereto is clearly shown. 7

The spindle driving means embodies in the present invention a driven friction disk C which is mounted on the stem B so as to rotate therewith and also be capable of being sli'dupwardly and downwardly thereon, as indicated in Figures 3 and 4. The connection between the disk C and the spindle B embodies a clutch face 6 on the disk G and another'clutch face 0 on the spindle B. The clutch faces are of suchextent that the disk C may be raised and lowered without throwing the clutch faces out of engagement with each other. Therefore, the disk C is always in driving connection with the spindle B. i/Vhe'n the bobbin winding unit is in operative condition, the disk C rests upon and is directly driven by a friction drive wheel D, as'shown in Figure 4. As soon as the disk C is slightly lifted, the rotation of the spindle B ceases.

The mean's for raisingan'd lowering the disk C embodies a two-armed lever E, said lever comprising an upperarme and alower curved arm 0. The lower arm a carries an anti-frictionuoll'er f which bears against the under side of the friction disk 0. The upper arm 6 carries an anti-friction roller f which bears against the working face 9 of a'cammember G, the latter beingprovided with an operating handle g. The cam face '9 isqi'iadr'ant-shaped and is formed on the highest portion thereof with. a dwell surface 9 andwhen said dwell s'uface is in engagement with the roller 7 the lever E is held in its disk-lifting position. The parts will beheld in this position untilthe -cam G is turned in the reverse direction for lowering the disk C. The hub of the cam G is rotatable axially around and upon th spindle B andrests upon the upper bearing a A collar h is fast on the stem B above ill the cam G, said collar h resting upon the cam. Another collar h is fast on the stem B just beneath the upper bearing The collars it and it prevent e'ndwis'e movement of the stem B and thus said stem or spindle is prevented from moving upwardly and downwardly.

By reason of the construction above described the bobbin may be wound with the utmost accuracyand with an even tension on the yarn throughout its entire length from the inside tot-he outside-layers and from base to tip. The yarn must be laid in even layers on and around the bobbin, thereby assuring an even thickness in the winding and enabling the yarn to be built up on the bobbin, controlled from the package itself. When the rotation of the spindle is stopped by turning the cam, the bobbin remains always at the same elevation, it being impossible for the bobbin spindle or stem to moveeither in an up: ward or a downwart. direction. The result is a bobbin evenly wound and free from bumps andthere is no liability of the, yarn being unduly stretched, which would cause the builder stem to bend or theyarn package to be dented.
